Applications

ISCO-Optic's Ultra MC series lenses are used in professional cinema projection for both 35mm and 70mm film. The Double-Gauss design — a six-element optical layout symmetrical around the aperture stop — delivers high resolution across the full image field and is a classic choice for projection optics requiring even illumination and low distortion. The Ultra MC designation indicates multi-coating on the lens elements, which reduces internal reflections and flare in a high-light-flux projection environment. The 110mm focal length places this lens in the mid-range for large-format cinema halls and drive-in theaters. These lenses remain in active use in venues still running 35mm or 70mm film, and are also sought by collectors, optical engineers, and cinematographers working with vintage projection equipment. ISCO-Optic (also marketed as ISCO-Göttingen) has been a German precision optics manufacturer since the mid-20th century, producing lenses for cinema, anamorphic projection, and industrial imaging.
